Referring to Fig. 1, X is an ordinary mold beard/plow adapted to turnthe" furrow and i lay the slice of sed upside dwn.

Fig. 6 is ahorizontal sectional detail on line 6-6 of4 Fi 3 v and'Figs 7., 7a and7*" are details of modi edits constructien, butasshown Figs. 3 and 5, itconsists ofy a hub provided with anumber.' of cutting rbladesset-obliquely,

like Apro eller blades, and of any desired numberan size. This plowhead" is'given,

vthrou h the shaft B; -thegears hereafter descri ed, arotation in the-directionof the arrow in' Fig. 2 which causes thelower. half ef thehead to move in harmony withthe ing direction of the slice of sodv beingturned over by the moldboard, thus helping over. the sod,which'sometimeshas a tendencyto drop back again into the furrow withoutbeturned The rotary head insures then `complete inversion of thesodandthe rotting e/ grass and weeds and of the f t roots, and also., atthesame time, cuts or' slices transversely the sod as it is turned andpulverizes and breaks up or comminutes the earth-like a harrow andgrinds'u and''tears loose all roots,thusthe ying of tle g ""1" Q.

shaft e am a bevel ear F'xed on theiagxl of two wheelsnlfll4 The axialshaft B turns in along sleeve bearing D held inthev cross bar E ofthemain frame of the plow.

The outerjend of. the shaft of the head is tiff supported by a verticalbar-I, see Fig. .2,

which has a bearing in which the shaft turns.

This vertical bar is 'arranged nearthe middle f of the'shaft and theupper end of this bar is of a series of holes 4in a late. Figs,

This stay -bar has a horizontal series of holesand a wedge sha ed lling block 'i4 is arranged'b'etween the ower end ofthe vertical bar I and the stay bar-i3. These connections are designedto provide means'. of adjustment for the plow head in two directions'.Thus when it is desired to adjust the rotary head A farther to the rightor left the upper screw threaded endv ofthe vertical bar I 1s adjusted.to the right or left in one of the holes'in the win plate and the bolti2 at the lower end is a justed' also toa-ight or .left in one of theadjusted in-one of said holes f/to correspond holes in the horizontal'.stay bary fia.. To raise o r lower the plow head, this .is ermittedholes 'i' in :the lower end, thebolt 'i2 being to the up and downadjustment of thebar I.'

The revolvin 'head it `will be 'seen has therefore three a just-ments,rst a-lon .'tudinal sliding adjustmenton' the axialsaftforward or'backward in the same horizontal I alsol combine seedin and plantingdevicesline; second, an; up. and down adjustment according to thethickness of sod being turned, and third a right and left lateraladjustment accordi to the width of slice and movement require vto turnit over.

'The adjustment of the -outer end of the head and axial shaft involvesbut a slight'v lateralmovement for the inner end of the axial shaft,which does'not interfere with the meshing of the ears and onlyrequiresalit- 'tie loosenes's or ee space in the c ross bar E- ;where the sleevebearing D passesthrou h it.

In connection with the 4rotat-ing plow4 ead as follows. A shaft Fig. 5',isp-arranged in bearings in the main frame just behind' and parallelwith the axle G. A bevel gear N meshes with the bevel gear and turnsshaft M and on this shaft is a seedwheel' L i rotating beneath ar seedbox K, Fig.. 1. A

The horizontal furrow lopener J'o ens the furrow and thev seeddropped by t e seed wheel pass down achute O into the furrow. f Acoverer P, Q, R, follows and covers the seed. The part P of the 'covereris avertical series of horizontal parallel and pointed blades, see Fi 6,to which are attached'two vertical si e on a horizontal axis between therear-.ends of blades AI scoop off clods and bring the earth over theseed to a flat level, thesides Qprevent. clods from rolling back vafterthe seed have 'beenthus covered and the.: concave grooved roller,following, presses down the earth strongly on the sides and lightly inthe middle, forming two little trenches which form drains for water 'andwithout making a hard crust on to of the seed; The creases left bythisroller a o, form a marker to show where to plant the next row the screwnut and the'vertica series ofV vdinally on the shaft.

Supported on the rear endl of the framework I is a driver-s seat Sand avertically adjustr able sun shade T. This'seat is arrangedin sions helddbwn by springs W belowl the main frame and headed lbolts I:v -whichextendthrough. saidl frameand have their heads above the treadle bars.

-80 n The forward ends U of these .treadle bars are ben'tfupwardl'y 4andextend to the plow handles and have' an 'adjustable connection Zwith-the same. By -A means of the feet'on thetreadles U, the plowhandles may be raised'fo'r lowered and swung slightly from side .to sideas 're uired by the ordinary managementv of a mol board plow, the feetand 'hands of the plowman both cooperating to .permit this' result andthussecuring perfctf'control over the plow.

From -the foregoing descriptionl it will be seen that'I have provided amachine which plows. the sod, harrows the furrows, plants the seed andcovers themall in one pass of great economy of labor andteams.
